1 awesome ee'vma Application filed, December 1, 1922. Serial no. 604,266.

To all whom it may Yconc'em:

Be it known that I, WALTER J. RUnoLrH,

a citizen of the United States, and a resident of Chicago, in the county of Cook and State 5 of Illinois, have invented certainnew and useful Improvements in Adjusting Devices, of which the following is a specification.

My invention is concerned with adjusting devices, and is designed 'primarilyto pro- 1 duce'such adevice: as can bequicklyinstalled on either the instrument'board (if one is etsployed) or onth'e dashboard of a Ford automobile and .used to control the mixture by determining the exact adjustment of the carburetor gas needle;

Toillustrate my invention, I annex hereto a sheet of drawin gs, in which the saine reference characters are used to designate :ideiitical "parts in all the figures, of which,

Fig; 1 is a perspective view withsome of the parts broken away, "showing my invention as applied to the instrument board;

Fig. 2 is a plan viewer the dial member;

Fig. 8 is a view r01 the same as seen from 25 the under side of Fig. 2';

Fig.4 is a detail in central vertical section through the gear-supporting bracket and gears; and

Fig. is a perspective view of a part thereof showing the dial adjusted on the dashboard.

Referring to Fig. 1, 10 is the instrument board, if one is employed, 1.1 is the dashboard having the customary slot 12 therethrough, and 18 is the carburetor of the engine for the Ford automobile. The carburetor-gas needle 1 1 is threaded in the top of the carburetor and is provided with the rose head 15 having the apertures 16 therein. Prior to my invention, the carburetor adjustment has been controlled by the rod 17 having a fork 18 on its lower cendextending through the holes 16, and, with the rod extending up'through the'slot 12-and term-inating in a ring by which it was manipulated. So much of the apparatus isold, and, per se, forms no part of my invention.

In order to readily make a more perfect adjustment of the position of the needle 14, I provide the dial member 20, which preferably consists of a sheet-metal plate having the body portion thereofsubstantially semicircular and with the graduation E21 thereon. I preferably mark the central graduation 0,

and to the left I use the odd numbers 1, 3, 5 and 7 andto the right I use the even numhers 2, 1, 6 and 8. The connectionsare adjusted so that when the pointer 22 stands opposite 0, the needle 14 is set for the average mixture at which the engine will 'ordi narily run, and when it is turned to the left, the needle is unscrewed "and a richer mixture furnished, so that it is preferably inarkeCWRich? below the 7 and Lean below the8. Thebody 2O ofthe dial is provided with a pair oi apertures for the screw bolts23, and also has the flange 24 turned at right angles to the body, and provided with apertures 25 to be employed as hereinafter described.

Co-operating with the dial member is the supporting plate, "preferably made of a sheet-metal stamping, and consisting of the rectangular body portion 26 having a pair of apertures therein for the screws 27, and with the flange 28 extending obliquely therefrom, and provided with a pair of apertures for the short screw bolts 29 seen in Fig. 5. The body 26 is preferably provided on the side opposite to the flange 28 with a short flange 30 extending at right angles to said body. Where the instrument board 10 is employed, the dial is adjusted by placing the parts in the positioii shown in Fig. 1., and passing the screw bolts 23 through the apertures in the body portions of the dial 220 and the supporting plate 26, and cli imping the edge of the instrument board 10 between said members by the action of the nuts on the screws, which pass below the bottom of the instrument board, and

thus obviate the necessity of doing any boring in said board to locate the dial plate in position. The pointer 22 has the hub or socket portion 81 in which is secured the end of theshaft 32 which is journaled in opposed apertures, not seen, in the body portions of the dial 20 and the supporting plate 26. Said rod 32 extends through the slot 12, and is secured by the set screw 33 in the hub 34 of the bevel gear-wheel 35 meshing with the bevel gear wheel 36 having the hub 37 in which is secured the upper end of the above-mentioned rod 17 by the set screw '38. It will be understood of course-that the rod 17 has had the ring 19 cut off and shortened up to the proper length so that it will extend downward from the hub 37 and have its fork 18 cooperate with the apertures 16 in the cross head. 15 in the customary manner.

To support the gear wheels 35 and 36, I employ the bracket shown, which consists of a sheet-metal stamping having the two body portions 39 and 40, which diverge from each other at the proper angle to give the wheels 35 and 36 the desired angular relation. These wheels" preferably consist of circular sheet-metal stampings with the teeth out on the edges and turned up slightly as shown, and said wheels are secured on the shoulders 41 of their respective hubs by swaging over the ends of said reduced portions forming the shoulders. Below these shoulders 41 are other shoulders 42, the reduced portion between the shoulders 41 and 42 furnishing the bearing surface for the hubs which are journaled in apertures 43 formed in the bodies 39 and 40 for this purpose. The bodies 39 and 40 are connected by the web portion 44, which is preferably trough-shaped in section, and at the top of the bracket I place the flange 45, which has a pair of apertures therein for the screws 46 by which the bracket is secured in place on the rear of the dashboard 11. The flange 45 is connected with the body portion 39 by the web 47, which is of suitable shape to support the body portions 39 and 40 in the desired relation to the rear of the dashboard 11.

Where the instrument board 10 is not employed, as illustrated in Fig. 5, the gearsupporting bracket is mounted as before, but the shaft 32 is shortened substantially and the supporting plate 26 is secured to the front of the dashboard 11, as shown in Fig. 5, by the screws 27, and the dial is secured thereto by having its flange 9A overlap the flange 28 and securing the two flanges together by the short screw bolts 29.

lVhile I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by. the state of the prior art.
